Theory of Machine Relationship between the number of links (L) and number of pairs (P) is P = 2L + 2 P = 2L + 4 P = 2L - 2 P = 2L - 4 P = 2L + 2 P = 2L + 4 P = 2L - 2 P = 2L - 4 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The ratio of height of Porter governor (when length of arms and links are equal) to the height of Watt's governor is (where m = Mass of the ball, and M = Mass on the sleeve) m/(m + M) (m + M)/M M/(m + M) (m + M)/m m/(m + M) (m + M)/M M/(m + M) (m + M)/m ANSWER DOWNLOAD EXAMIANS APP
